In this article, we review virtual private networks, or VPNs, one of the most important measures for teleworking, as they allow a connection to the organization through secure networks, and the advantages they offer, as well as additional security recommendations to help ensure cyber security.
Specialized blog with informative contents destined to a public with marked technical profile, in order to improve knowledge and create a culture about the security in Internet.

The Modbus protocol, in its TCP version, was not developed with cybersecurity capabilities in its communications. For this reason, many researchers have studied the different possibilities that could be undertaken at the technical level to incorporate a security layer in it, giving rise to a new version of Modbus/TCP called secure Modbus/TCP, which will gradually begin to be implemented in industrial communications.
Over the last few years we have seen how electric vehicles have experienced a boom in terms of their development and retail and, along with them, the deployment of their charging points. In this article we will discuss a series of requirements, in terms of security, that should be implemented in these charging stations in order to ensure their security.
Electric charging stations are increasingly used in urban furniture in cities. Electric cars and their need to be charged are a reality. Because of this, there is an increase in supply points that depend on specific protocols and communications for these stations.
Today, it is common to find SIEM deployed in the IT infrastructures of all kinds of organisations, to be able to monitor and analyse security alerts in applications, systems, network devices, etc. However, though time and resources are being invested in industrial environments, it is still unresolved.
The main security standards and best practice guidelines in industrial cybersecurity include as a requirement the need for a user authentication system. The options involve implementations in each device of this system or being integrated into a centralised user authentication system. One of the most-used options is the use of the LDAP protocol, but there are a number of points to consider in the design phase, which are key when implementing a specific centralised user management system for industrial control systems, under LDAP.
In recent years there has been an increase in interconnectivity between devices thanks to the Internet of Things (IoT). This has affected all sectors, including industry, which has been involved in an era of connectivity of industrial devices. This concept is known as the Industrial Internet of Things (IIoT).
A BusyBox is software or a program that combines several functionalities in a small executable. This small tool was created for use in integrated operating systems with very limited resources, and they are usually used in control systems. But, as in all tools, you have to know what security level they have and if it can be improved.
Control system networks have grown immensely in recent years, something similar to what happened with the explosion of IT networks in the 1980s. This growth is happening somewhat chaotically, promoted mainly by productive needs and by the lack of joint definition of network administration managers for IT and OT, instead of doing it by thinking of the future, scalability and security.
ICS environments are made up of very heterogeneous machines, with large differences depending on the system we are dealing with. Some of these systems have very strict response time requirements for their correct operation and therefore use real-time operating systems. Throughout this article we will see what real-time operating systems are, how they work, and we will propose hardening measures to reduce the likelihood that these devices will suffer a cyberattack.
